I am applying for tenure-track positions in the US and Canada. I did my PhD in the UK during which I ran tutorials for students for a few years. However, I never received any official feedback or evaluation and now find myself looking at an application asking for teaching evaluations.
What are my options? Would it be inapropriate to search for my former students and solicit feedback? It's now been over a year since my last cohort. I know one went on to do a PhD in my former group, how would it look if I asked them to write a reference letter for me?
